       8. A hearing aid according to  claim 1 , wherein the cover comprises an inner structure shaped to fit at least a portion of the outer structure of the battery, wherein the surrounding structure extends from said cover around an outer contour of said battery. 
     
     
       9. A hearing aid according to  claim 1 , wherein the surrounding structure is at least partly connected to the housing and/or to a structure arranged in the housing by means of a third attachment member, said third attachment member being configured as a magnetic element arranged in a free end of said surrounding structure. 
     
     
       10. A hearing aid according to  claim 9 , wherein the third attachment member is arranged in a non-zero distance from the cover. 
     
     
       11. A hearing aid according to  claim 10 , wherein the third attachment member is arranged in a non-zero distance along a longitudinal axis (X) of said cover or of a transverse direction (Y) perpendicular to said longitudinal axis (X) from said cover. 
     
     
       12. A hearing aid according to  claim 1 , wherein the thickness of the surrounding structure is 0-300 μm. 
     
     
       13. A hearing aid according to  claim 1 , wherein the width of the battery drawer corresponds to the sum of the diameter of the battery and two times the thickness of the surrounding structure.
